  1. 1. Application of ring statistics to characterise graphitisation of carbon fiber heat shields under atmospheric re-entry conditions

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Hamish Keay; [2023]
    Nyckelord :Aerospace; Heat shields; Re-entry; Graphitisation; Carbon fiber; Carbon phenolic; Ring statistics; Graph theory; Molecular Dynamics; återinträde; grafitisering; kolfiber; kolfenol; ringstatistik; grafteori; molekylär dynamik;

    Sammanfattning : Carbon fibers submitted to high temperatures (>2000 °C) experience a permanent increasein their thermal conductivity. This change has been attributed to a change in the molecularstructure due to graphitisation. LÄS MER

  3. 2. Effects of reconstruction parameters on the image quality and quantification of PET images from PET/MRI and PET/CT systems

    Master-uppsats,

    Författare :Ali Amena Hussain; [2022-03-09]
    Nyckelord :Medical physics; PET CT; PET MRI; OSEM; BPL; NEMA IQ; positron emission tomography; magnetic resonance imaging; computed tomography; ordered Subset Expectation Maximization; The Bayesian Penalized Likelihood;

    Sammanfattning : Aim: To study how reconstruction parameters affect the positron emission tomography (PET) image quality and quantitative results for the different lesion to background radioactivity ratios in three different PET systems. Introduction: Multimodality imaging that combines magnetic resonance imaging (MRI) or computed tomography (CT) with a PET system can produce medical images containing both functional and anatomical information.

  4. 3. Particle Segmentation In Transmission Electron Microscopy Images

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Lisa Svens; [2022]
    Nyckelord :;

    Sammanfattning : When pharmaceutical companies develop new drugs or vaccines there are large amounts of data in the form of images that need to be analysed, and any automation of that process is helpful to reduce time. These analyses could be for example concentration, decomposition, or classification, and essential to all these is high-quality particle localisation and segmentation. LÄS MER

  5. 4. Amodel for the internationalisation of e-commerce scale-ups : Represented by a conceptual prototype of a digital tool that assists firms in localising its business model to better address local customer needs

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Rita Nordström; [2022]
    Nyckelord :Internationalisation; E-commerce; Digital handbook; Conceptual prototype; Scale-ups; Internationalisering; E-handel; Digital lathund; konceptuell prototyp; tillväxtbolag;

    Sammanfattning : The internet has transformed the way people sell and buy goods and services. E-commerce is a fast-growing industry with low barriers to entry, making it easy to start an e-commerce business – but scaling it is a whole other matter. One common scaling method is international expansion. LÄS MER

  7. 5. Autonomous Landing of an Unmanned Aerial Vehicle on an Unmanned Ground Vehicle in a GNSS-denied scenario

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Alexander Källström; Albin Andersson Jagesten; [2020]
    Nyckelord :Unmanned Aerial Vehicle; Unmanned Ground Vehicle; Autonomous Landing; Ultra-Wide Band; Proportional Navigation; GNSS-denied Scenario; Gazebo;

    Sammanfattning : An autonomous system consisting of an unmanned aerial vehicle (UAV) in cooperation with an unmanned ground vehicle (UGV) is of interest in applications for military reconnaissance, surveillance and target acquisition (RSTA). The basic idea of such a system is to take advantage of the vehicles strengths and counteract their weaknesses. LÄS MER
